Sfdoom

sfdoom (also called SF-Doom) is a source port created by Simon Howard (Fraggle) which was a forerunner of SMMU. It was derived from DOSDoom by Chi Hoang.

History
sfdoom contained several features that would later be rewritten in SMMU, including a console, colored lighting, start map, and basic scripting. SMMU, though not directly derived from sfdoom, was intended as a rewrite of the project, and started out initially with the same name as its forerunner.

Legacy
After SMMU development was started, sf-doom was left abandoned. The last released version was 1.21, released on February 5, 1999.
